Drainage of left hepatic vein into coronary sinus associated with other systemic venous anomalies.

Abstract

This report describes a case with double hepatic venous drainage into the right atrium. The right hepatic veins, the inferior cava, and the pulmonary veins drained normally. The

Drainage of the Left Hepatic Vein into the Coronary Sinus, a Rare Intraoperative Finding

“…An English literature search yielded reports of only four living patients with this anatomy. There is an association with other congenital venous and cardiac anomalies . Persistent drainage of the left hepatic vein into the coronary sinus usually is an incidental finding.…”

Anomalous left hepatic vein draining into coronary sinus imaged with multidetector computed tomography

“…This venous anomaly can potentially lead to technical difficulties during trans-coronary sinus interventions (Vuran et al, 2011) and cannulation of the coronary veins for certain procedures, such as biventricular pacing. Finally, anomalous hepatic venous connections can be associated with other anomalies, such as subaortic valve stenosis (Buehler et al, 2011) and other systemic venous maldevelopments (Van der Horst et al, 1971;Buehler et al, 2011).…”

Duplication of the superior vena cava associated with atrial termination of the left hepatic vein

“…The venous system in the fifth gestational week (Figure 4a) consists of three types of the vessels: the vitelline (omphalomesenteric), umbilical and cardinal veins. 1,4,7,8,11,13,16–18…”

“…The persistence of a left vitelline vein connection, i.e. the left hepatocardiac channel (Figure 4a), causes the LHV to drain into the right atrium, either directly or into the CS 1–5,14,16 or, very rarely, into the left atrium with a possibility of paradoxical embolism. Hepatic vein anomalies, in addition to the accompanying LSVC, can also be associated with an IVC duplication, IVC continuing with the azygos vein, and the intrapulmonary right-to-left shunt.…”

“…1–6,11–15 The combined venous variations we found in one anatomic specimen were published in medical literature only three times so far. 3, 7, 16…”
